This brush has the perfect shape for the precise application of color in the crease, it is perfect for smudging along the upper or lower lash line, for applying color to the inner corner of the eye (near the tear duct), as well as creating the perfect outer "V."
According to my box, this brush is made in the U.S.A., and is made with care and quality parts. I have only used it a few times over the last couple of days and must say that I am quite pleased with the results so far.
I would be remiss if I didn't make the obvious comparison to the best known "Pencil Brush," the MAC 219. The MAC 219 is a little bit heavier, with a slightly more pointed tip, a black wooden handle and a nickel-plated brass ferrule. It also has natural bristles but they are quite light which allows you to see precisely how much pigment you are grabbing- which can have its advantages.
The MAC 219 costs $24.50 and is made by hand.
The Sunday Riley Eye Definer Brush costs $28.00 and is made by hand.
They perform all of the same functions, and are both nice quality brushes. However, for those in need of a finer pointed tip the MAC 219 will be more effective. However, if a finer point is not necessary then you will be very happy with the Sunday Riley Eye Definer Brush.
I think that the perfect scenario would be to have both of the brushes. For me, there is no point in choosing between them-- I think a good kit should have both!
